VELOCIPEDE.

SPECIFICATION forming part ot Letters Patent No. 257,415, dated May 2, 1882.

Application tiled January 18, 1882. (No model.) A

To all whom it may concern.-

Bc it known that I, O'rro UNzrcKEn, of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in'Velocipedes; and I do hercby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part ot this specification.

The nature of my invention relates to velocipedes ofthe style known as tr-icycles, and it is my object to produce such a vehicle that is propelled by the'feet and steered by one hand, and can be used by males and females, and can be adjusted to be suitable for an in- .fant or adult.

Therefore my invention consists in the devices and combination ot' devices hereinafter described, and pointed out by the claims.

In the accompanying drawings, Figure l represents a perspective view of the tricycle; Fig. 2, a longitudinal vertical section through one side ofthe frame; Fig. 3, a vertical crosssection through the center ofthe standard portions ofthe frame and through the seat, and Fig. 4 a cross-section ot' the seat-board and fastening for the same.

Like letters represent corresponding parts in all the figures.

A denotes the frame, composed of a single piece of wroughtiron pipe or tube, that is bent horizontally to the shape of the letter U, with both shanks bent again at about their middle, so as to form two parallel standards that are rectangular with the U-shaped frame. The i'ront or connecting portion ot' this frame A, I have marked o, the horizontal portion of the two shanks b, and the standards c.

Bis the,axle,journaled in boxes I, which have each a sleeve formed to one end, that is passed over the standard c of frame A, and is rigidly secured in its position by a rivet passed through the sleeve and standard.

GC are the two main Wheels. The wheel() is rigidly mounted upon one end of axle B, and hasa sprocket-wheel, d, secured upon or against the inward end of its hub, and the wheel G is fitted loose upon the opposite end of said axle B, so that both wheels can turn ata diiiferent velocity, or one can turn while the other one is not moving.

Upon the middle of the front portion, a, of frame A is sleeved and rigidly secured an arcshaped bracket, I), having a vertical hub, m, formed to its forward end. Through this tube is passed the pivotal shank of the bifuroated standard E, in which the steering-'wheel F is pivoted.

To the upper or projecting end ot' the pivotal portion of the standard@ is lsecured the arm G, having a cross-handle, by which the direction ot"t`he wheel F can be regulated, and` the vehicle can bej steered to follow the intended course.

His a cross-bar having tubular ends rectangular to saidfbar. 'These tubular ends are passed over both standards c of frame A, so as to slide vertically thereon, and are supported upon coiled springs e, also passed over the standards c, and resting upon collarsf, that can be adjusted to a higher or lower position by set-screws. By the very simple arrangement of cross-bar H, springs c, and adjustable collarj'it will be seen the seat has not only an elastic support, but it can be varied as to height for accommodating different size persons.

The seat-board I issecurcd upon thecross-bar H by two saddle-platestg/,and boltslt, and this seat-board is provided with a back-support and side rails,in the manner of a sulky-seat, Y

and is to be provided with a cushion.

J4 is a double crank having pivotal pedals t', aud being pivoted in journal-boxes j, that have sleeves which are passed over the portions b of frame A, and are adjustably secured there on by setlscrewsc.

Upon one projecting end of the crank-shaft J is mounted a sprocket-wheel, L, so as to be in line with sprocket-wheel cl of wheel O,.and au endless chain, M, is stretched over both these sprocket-wheels L and d, that will transmit the motion from the crank shaft J to wheel O.

A guard-plate or fender, N, having a sleeve or clamp formed to one end, so as to be adjustably secured upon the portion b of frame A,

coversA the sprocketv\'heel L and protects it against injury, or that the dress ot' a girl or lady riding upon the tricyole may not come in contact, to be soiled or to be caught between the chain and Wheel.

Y Such a velocipede or tricycle is easy to handle without much practice, gives a comfortable seat to the person occupying it, allows ready adjustment of the seat vertically for differently-sized persons, and for keeping the chain taut, and will permit the turning ot'short curves.

The top ends of frame-standardscmaybe provided withornamental knobs, and the wheels may have rubber tires to make their movements noiseless and to increase the traction ot' the drive-Wheel.

The Whole construction of thc vehicle is such that with the leastweightot' material the greatest strength is'obtained, and that its shape and appearance vis light and pleasing.

Instead of making the lever G rigid with the end of the hifureated standard E, it may be connected thereto by a universal or svvivd joint, in a manner that by a torsional movement ot theleverG the wheel F can be turned to follow either direction.

What I claim is` A tricyele composed ot' frame A, consisting cfa single piece oftuhing horizon tally bent into U shape, a b, and having standards c c, axle B, journal-boxes l, having a sleeve at one end to adapt the same to pass over said standards c, wheel C, rigidly mounted upon one end of the axle, and having sprocketwheel d,.wheel C', fitted loosely upon the other end of said axle, crank-shaft J, having sprocket-wheel L, and endless chain M, arc-shaped bracket D,

having vertical hubm,bifurcated pivotal stand-- ard E, steering-wheel F, cross-bar H, having tubular ends to adapt the same to be passed over the standards c, coiled springs e, adjustable collars f, and seat I, secured to said crossbar H, substantially as and for the purpose set forth.

2. The combination of the frame A, having standards c, cross-bar H, having end hubs to adapt the same to be passed over said standards c, seat-board I, secured to said cross-bar supporting springs c, and adjustable collarf, all constructed and arranged substantially as shown and described.

3. The combination, with the frame A, having standards c, brackets l, sleeved upon said standards and forming the journal-boxes for axle B, drive-wheel C, with sprocket-wheel d, rigidly secured thereon, and wheel C', loosely pivoted thereon, of the double-crank shaft J, pivoted in journal-boxesj, also sleeved upon such frame A, and adj ustably secured thereto by set-screws k, of a sprocket-wheel, L, mounted upon the end of such crank-shaft, and ot' an endless chain, M, stretched over both sprocket- Wheels L and d, all substantially as set4 forth.

4. lIn a tricycle, the guard-plate or fender N, having a sleeve or clamp formed on one end,to adapt the same to be adj ustably secured to the frame A, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I affix my tvvo Witnesses.
